"With the Samsung Galaxy S4 presumably coming soon, many are excited about the possibility of running a more stock Android-based experience, like CyanogenMod, on the hardware. It looks like that's going to be a slower transition than many were hoping, as the current Samsung CM maintainers have said that they have no plans to support the device." If you like custom ROMs, don't buy Samsung. As simple as that.

Just because the current maintainers have no plans doesn't mean a new one won't come along. Plus there will always be "debloated" stock based roms that will be close to stock. This is the case with many less popular devices. I though Cyanogen got a job with Samsung, strange that they would be so poor with releasing source. What about the Nexus 10, doesn't that have a exynos processor?
